In the journal Angewandte Chemie, American scientists have now introduced a two-step, one-pot conversion of CO2 and epoxides to polycarbonate block copolymers that contain both water-soluble and hydrophobic regions and can aggregate into nanoparticles or micelles.http://phys.org/news/2015-07-polymers-greenhouse-gas.html

The test, which presaged the atomic bombs dropped on Nagasaki and Hiroshima, Japan in August 1945, forever changed the course of world affairs. Subsequent nuclear explosions, and the radioactive fallout they produced, quickly gave rise to worries over the dangers of radiation.http://phys.org/news/2015-07-postwar-american-mindfrom-toworry.html

Although its energy supply system has served it well in the past, the country is now looking to turn away from its reliance on nuclear power and seeks to compensate for the energy lost from hydropower as a result of climate change. In the latest issue of the Bulletin of the Atomic Scientists, published by SAGE, Dominic Notter of Empa discusses how the country aims to address this transition, finding a new supply mix that combines energy conservation, greater efficiencies, alternative energy sources, the "smart grid", and the introduction of new technologies, so that Switzerland can secure its energy independence for the future.http://phys.org/news/2015-07-energiewende-alps-switzerland-transition-nuclear.html
